Macronutrient And Energy Case Study

Good Essays

Part I- Macronutrients and Energy
1. Janine and Mitchell are talking about
a. Protein is a molecule that contain nitrogen, carbon, hydrogen, and oxygen. Protein is used to give energy to the body because of the amino acids found in protein. Some examples of good sources of protein are milk, eggs, different meats, and even in vegetables.
b. Carbohydrates are molecules that contain carbon, hydrogen, and water. Carbs are used for energy; glucose and glycogen provide about half the energy muscles and other body tissues use. Some examples of carbohydrates are whole grains, vegetables, and fruits.
c. Fats, also called lipids, are molecules that contain carbon, hydrogen, and oxygen. Lipids can provide more energy than carbs because they have more …show more content…

When Janice made the statement about carbs and getting cranky, she was right. Carbohydrates are responsible for giving the brain energy, thanks to glycogen and glucose. The nervous system uses glucose by sending it to the blood stream to be sent to the rest of the body, especially the brain.
3. Too much protein can be harmful for the kidneys because it can cause the kidneys to overwork, which can lead them to secrete too much ketones and it can lead to …show more content…

Set point theory is the idea that the body maintains its weight with controls in the body telling it to do so. Toxins are not involved in the set point theory. Body size and homeostasis are related in the way that the body does not want things to change, it wants things in the body to stay as constant and the same as possible, which is one reason why it is so difficult to lose weight.
3. Metabolism is the sum of all the chemical reactions that go on in living cells. Metabolism has a lot to do with energy balance and body weight because it determines how fast the cells have chemical reactions occur. If the metabolism of someone is faster than the metabolism of someone else, then that person burns fat and uses energy faster than someone whose metabolism is slower.
4. This statement is true because when the body has a high muscle mass, the cells of the body have to work harder and faster to burn fat and create energy. This requires that the person eat more than someone with less muscle because they have a higher metabolism.
5. A diuretic is something that is used for people trying to lose weight. The effect of diuretics can be helpful or harmful on the body, depending on how it works within the body. A diuretic effects homeostasis because it changes chemical reactions in the body, which makes it so that the body loses fluids easier and
